摘　　要：简单分析了集成门极换流晶闸管(IGCT)门-阴极结构和工作原理,并在原有均匀矩形排布和均匀圆周排布的阴极图形基础上提出了一种新的排布方式——梳条分区复合排布。它不仅增加了IGCT阴极的有效面积,增大了电流容量,而且减小了热阻,改善了门极电流通道。The gate-cathode structure and operation principle of IGCT are analyzed simply.Then a novel finger arrangement manner for cathode layout,finger partition composite arrangement,is supplied based on the original uniform rectangle arrangement and uniform circle arrangement.In this way,IGCT cathode effective area is expanded and current capacity is enhanced;furthermore,thermal resistance can be decreased while gate current channel is improved.

关 键 词：IGCT 梳条排布 分区复合排布
